To aZZ whom it nuty concern.-

Be it known that 1, Firms J. FORRESTER, of the city of St. Louis, State of Missouri,have invented certain new and useful Improvements 5 in Soap-Pressing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

This invention relates to improvements in IO a soap-pressing machine; and it consists of the novel construction, combination, and arrangement of parts, as will be more fully hereinafter described, and set forth in the claims.

One object of this invention is to construct I 5 a machine with a series of levers operated by eccentrics for conveying the soap in communication with dies,suitably pressing the same, and discharging the soap upon the same belt on which it entered, and then conveying the 2o soap to a table, where the same is wrapped.

Another object is to provide suitable levers operated by arms which communicate with and are operated by segments to engage the bar of soap when in alinement with the pas- 2 5 sage in front of the die, whereby the soap is pressed in the mold and discharged by the same operation or back again onto the belt and delivered to the wrapping-table.

Referring to the drawings, Figure 1 is a side elevation of my complete machine, showing the table partly broken away. Fig. 2 is a top plan view of the same. Fig. 3 is an end view of the machine. Fig. 4 is an end view of the table, showing the belt-adjuster. Fig. 3 5 5 is a detail view of the eccentrics and eccentric-operating arms. Fig. 6 is a top elevation of the belt-adjuster detached from the table. Fig. 7 is a detail top plan View of the levers used to feed the soap cake from the belt in communication with the die and mold. Fig. 8 is a detail side elevation of the spring-dog carried by the segmentoperating arms by which the soap-operating levers are manipulated. Fig. 9 is a top plan view of the same. 5 Fig. 10 is a detail view of one of the bars carrying the die, showing its connection to the eccentric-operating arms. Fig. 11 is a perspective view of the plate and arm used to disconnect the soap from the end of the die when delivered through the mold. Fig. 12 is a top plan view of the mold. Fig. 13 is an edge view of the same. Fig. 14: is a side elevation of the sprocket-wheel by which the lever, as shown in Fig. 11, is operated. Fig.

15 is a front view of the same. Fig. 16 is a perspective view of the die and a portion of the bar by which it is carried.

In the drawings I construct my machine with a table 1, mounted upon suitable legs 2, which are made of suitable material, prefer- 6o ably cast-iron in this case, and the said legs are connected together by the braces 3, which act as supports or bearings for the operating mechanism,which is located beneath the table.

In the braces 3 is formeda bearing 4, in which 6 5 is carried a shaft 5, upon which is mounted two eccentrics 6 and 7, and are driven by the pulley 8, on which is placed a belt of the usual construction.

To the brace 3, on each side of the central 7o shaft 5, is mounted a shaft 9, carrying arms 10, which are also provided with a curved arm 11, which comes in communication with the grooves 12 of the eccentrics by which said arms are operated.

Upon the top of the table 1 are provided bearings or guide-posts 13, in which are mounted and carried bars 14, provided with a slot 15, in which extend the arms 10, which are connected to a frame 16, which is carried by an adjusting-bolt 17, formed in the rear end of the bars 14, which is constructed to adjust the die 18, carried by each bar, which is necessary according to the thickness of the bar of soap to be pressed. One of said bolts 17 is provided with a spring 17 its function being to allow the bar let to be adjusted according to the thickness of the cake of soap to be pressed and also to give in case of an obstruction. Itis only necessary to have a spring 17 a on one of said bars 14, as the one to which it is applied has the principal action and the opposite bar is never varied. Between the dies is carried the mold 19, mounted in adj ustable supports 20, secured to the top of the 5 table 1. The mold 19 is constructed of suitable size to allow the dies 18 to pass therein and through which the bar of soap is passed after being pressed therein. Immediately in front of the mold 19, but a little beneath the same, is a plate 21, carried by a rod 22, having a downwardlyextending arm 23,

, operated by the eccentrics.

tendency to stick.

Upon the bar or guide-post 13 is mounted a curved lever 26, connected to a lever 27 by. a connecting-bar 28. The lever 27 is pivotally mounted upon the plate 27 boltedupon the guide-post 13, projecting inwardly over the space occupied by the belt 37, said lever provided with a projection 29, in which is fastened one end of the spring 30, and on its forward end is a flattened downwardlyextending arm 31, which is designed to come in contact with the cake or bar of soap, con; Veyingit inwardly upon the guard-plate 32 when said levers are operated by the arms The lever27 .is brought back into its normal position by means of the spring 33, having its inner end .secured to said lever 27 and its other to the guide-post 13, the purpose of which is when the lever is operated to convey the soap inwardly and release by the arms 10, the tension of said spring 33 bringing saidlever 27 in the position as shown in Figs. 2 and 7. 4

The spring 30, which is carried by the lever 27, is also secured to the projection 34, securely fastened to the guidepost 13, and this spring is for the purpose that when the'lever 27-.comes in communication with the 'bar of soap and in case the bar is somewhat larger than thecake the machine is set for the spring will allow the lever 27 to have a back pressure without materially injuring its parts.

i The lever 35 issecured to the guide-post 13 on the opposite side of the machine and is likewise provided with springs 36, one end secured to the lever 35 and its other to a projecting arm 36. the dog 39 coming in contact with the pawl 35*, pivotally secured in a brace 35", mounted upon the guide-post 13, its operation being similar to the levers previously described; but its actionis to come in contact or communication with the bar after it has left the 1 -mold 19, pressing it forward, so that said barv is placed upon the endless belt 37; where-- upon said bars are conveyed to the table 38,-

where the same are wrapped. These series of levers are operated alternately by means of the dog 39, mounted in an angular plate 40, suitably secured to the top of each of the arms 10, and is pivotally located therein and provided with a pin 41 on its under surface,

around which is placeda spiral spring 42, its

purpose being that when the arms 10 are op-j .erated the flat surface 43 of the dog comes in communication with the prong 44 ofthele- This lever is manipulated by I ver 26, pressing it forward, causing the levers to operate in the usual manner, as previously described, and when the dog 39 is carried beyond the arm 26 the same is allowed to pass said arm after it has fallen back to its normal position by allowing the dog 39 to pass underneath, its round surface 45 coming in contact with the under side of the lever 26, pressing it downwardly upon the spring 42, which allows the dog 39 to swing up or take its normal position when said lever is passed, and this action is repeated throughout the operation of the machine.

The endless belt 37 is mounted upon a roller 46, carried upon the shaft 47, being operated by a sprocket-wheel 48, being conveyed by sprocket-chain 49, secured to the sprocket- -wheel 25, mountedupon the driving-shaft 5.

'The belt is also carried upon the roller 50, secured to the end of the table 38. This roller is carried in two adj usting-rods 51, carried in a support 52, suitably secured to the edge of the table. This device is for the purpose of tightening the belt 37.

The table 38 is composed of. a top provided with a groove 53, through which said belt is passed, and oneach side of said belt and upon the table are located guards-54, extending a slight distance above t'heheight of said belt,

which are for the purpose of preventing the being conveyed from the machine. At each side of the table, underneath the top, is formed a shelf 55,0n which are placed the wrappers in which said bars of soap are wrapped. This is for the convenience of persons wrapping the bars asthey are delivered to them by the endless belt, as previouslydescribed.

The machine is provided with a tank 56,

wliich is located above the mechanism and contains water, whichis allowed to drip upon the passage-way where the soap enters before the die, the water causing said bar, to slip easily, because soap on many occasions is very dry and will stick to the belt or guideplate when not given sufficient dampness or moisture. At one side of the table is secured a guide-strip 57, which is. provided at one end With an outwardly-bent guide-strip 57 and said guide-strips extend asuitable height and are for the purpose of preventing the. cake of soap from falling from the belt 37. On

the table opposite the passage through which the soap is to pass to come in communication with the mold I place aguide-strip 58, which is also for the purpose as before mentioned.

The operation-0t this invention is as follows: The bars of soap are placed upon the section of the .belt (marked a) by hand at a .space of about six to eight inches apart, be-

bars of soap from falling from said belt when ing it forwardly upon the guard-plate 32. This lever is operated by the arm coming forward, its dog 39 coming in contact with the curved end 44 of the lever 26. After the bar is in this position the opposite arm 10 is brought forward by means of the eccentric carrying forward the bar 14, bringing the die in communication with said bar and pressing it into the mold 19. Both bars are brought forward very nearly at the same time, causing each die to press against the cake of soap while in the mold 19, and when pressed the said bar is forced out of the mold upon the 7 plate 21 by'meansof the rear die extending still forward, while the opposite die is moved backward, and when the cake is at the extreme end of the mold 19 the plate 21 is slightly raised by means of the downwardlyextending rod 23 pressing upwardly upon the cake of soap, releasing it from the edge of the die, and at this moment the arm 35 is brought forward by the action of the arm 10 pressing the bar of soap upon the belt 37, which is then conveyed to the table 38, where it is removed by the parties who place said cakes of soap in the paper wrappers. The cakes of soap are placed on the section a of the belt 37 at short intervals apart in order that each cake will not interfere with another while the lever is being operated backward and forward. This is generally arranged according to the judgment of the operator who places said cakes upon the belt.

The plate 21, which has been described, may be located on the top of the mold instead of underneath, as found best desired. In case a larger bar of soap is to be pressed the adjusting feature is done by tightening or loosening the nut upon the bolt 17, which communicates with the frame secured to the arms 10, which will cause the curved arm 11 to find the proper location in the groove 12 of the eccentric, thereby adjusting said movement to a shorter or longer stroke.
